The 143rd Pic of the Week takes us to Burlington, Iowa, and to this bridge, the Cascade. If there is one bridge a person should see in order to appreciate its structural beauty, fitting in a natural setting, it’s this structure. The bridge features a Baltimore deck truss and two Pratt deck trusses, all of the connections are pinned. The Baltimore span is the only known truss of its kind in Iowa, yet its construction and uniqueness has earned it national recognition in the form of the National Register of Historic Places. The bridge was built in 1896 by the Milwaukee Bridge and Iron Works Company, using Carnegie Steel as its provider for steel bridge parts. The design cam efrom the engineering office of Boynton & Warriner in Cedar Rapids. The bridge is suspended more than 60 feet from the ground, with supports from both sides of the gulch which the structure spans. A rather unique piece of artwork for a bridge lover and historian.
The bridge was one of the stops we made during the Historic Bridge Weekend in 2013 and this pic came from James’ bridge library. Yet its days may be numbered for the structure has been closed since 2008, to pedestrians since 2019. Residents living on the south side of the city have been battling to at least reopen the bridge for bikes and pedestrians, even if it means making the necessary repairs to do that. Yet the Burlington City Council has been unwilling to make even the modest repairs because of the lack of funding. Its cash-strapped mentality has resulted in much of its historic architecture either disappearing with the wrecking ball or simply sitting there until one incident that brings up the liability issue comes about and it eventually becomes a pile brick and steel. Its abandoned houses and buildings are matched with those in Glauchau, where BHC is headquartered, except Glauchau’s issue are owners buying historic buildings and simply leaving them sit without doing anything with them.
The winds of change are coming to Burlington, though. Already plans to replace the Cascade Bridge is going into motion, though when this will happen remains unclear, due to the question of funding, combined with the bridge’s status and the opposition to demolishing the rare structure to begin with. I’ve been doing some research and interviewing some people involved with the project and an Endangered TRUSS article is in the making.
Stay tuned for more details…..
